Embodiment 3

The layer 1 (L1) is the lowest layer and performssignal processing functions of various PHY layers. The L1 is called PHY301 in the present disclosure. The layer 2 (L2) 305 is above the PHY301, and is in charge of the link between the first-type communicationnode and the second-type communication node via the PHY 301. In the userplane, L2 305 comprises a Medium Access Control (MAC) sublayer 302, aRadio Link Control (RLC) sublayer 303 and a Packet Data ConvergenceProtocol (PDCP) sublayer 304. All the three sublayers terminate at thesecond-type communication nodes of the network side. Although notdescribed in FIG. 3 , the first-type communication node may compriseseveral protocol layers above the L2 305, such as a network layer (i.e.,IP layer) terminated at a P-GW 213 of the network side and anapplication layer terminated at the other side of the connection (i.e.,a peer UE, a server, etc.). The PDCP sublayer 304 provides multiplexingamong variable radio bearers and logical channels.
